class TGVScrollBar: public TGScrollBar


TGScrollBar and TGScrollBarElement

The classes in this file implement scrollbars. Scrollbars can be
either placed horizontal or vertical. A scrollbar contains three
TGScrollBarElements: The "head", "tail" and "slider". The head and
tail are fixed at either end and have the typical arrows in them.

The TGHScrollBar will generate the following event messages:
kC_HSCROLL, kSB_SLIDERPOS, position, 0
kC_HSCROLL, kSB_SLIDERTRACK, position, 0

The TGVScrollBar will generate the following event messages:
kC_VSCROLL, kSB_SLIDERPOS, position, 0
kC_VSCROLL, kSB_SLIDERTRACK, position, 0
